First of all, there is a layer of mucous tissue and nose hair on the inner wall of the nasal cavity, mainly to prevent dust from entering the trachea. Cleaning the nasal cavity every day will damage the mucosal layer in the nasal cavity and lose its adhesion and blocking effect on pollutants such as dust. It can be cleaned in 2-3 days. Of course, according to your own living environment.

The nose has nose hair and nasal mucosa, which can secrete liquids such as snot, which can effectively prevent dust from entering the respiratory tract, so it is not necessary to clean the nose every day. Too much cleaning will destroy the ecological balance.
The advantage of nasal washing is that the secretions of nasal cavity and sinus can be washed as clean as possible, which can reduce the contact between allergens, viruses and bacteria and nasal mucosa, thus reducing the stimulation to nasal mucosa and preventing and alleviating the symptoms of rhinitis and sinusitis.

In addition, after nasal irrigation, the secretions of nasal cavity and paranasal sinuses can be washed as clean as possible, and then drugs, including nasal spray and drops, can make drugs better contact with nasal cavity and paranasal mucosa, thus achieving better results. These two aspects are the most important benefits of nasal irrigation, in addition, it can also reduce nasal mucosal swelling and relieve nasal congestion.
If the nasal cavity is cleaned with normal saline regularly, the tiny pollution particles inhaled into the nasal cavity can be washed out of the body through normal saline to keep the upper respiratory tract clean.
If the patient is allergic rhinitis, the inhaled allergen can be washed away by nasal cavity cleaning with normal saline, which can reduce the chance of allergic rhinitis and relieve the symptoms of allergic rhinitis.
If chronic sinusitis has more purulent nasal secretions, we can wash all kinds of secretions in the nasal cavity with normal saline, which can restore the ciliary movement function of nasal mucosa and is conducive to the recovery of rhinitis or sinusitis. Normal saline does not play a direct therapeutic role, but plays an auxiliary role in treating various rhinitis.

Although it is good to wash your nose, you can't wash it every day. It's best to wash it every few days!
